To all it may coacem: 1,

a/citi'zen of 'the vUnited "States of, America',

' and a' resident of Brooklyn,-Kings county,

and State of 1lfl' ew- York; have invented'certain newand useful Improvements in Yibra f' tory Actuators, ofwhich theiollowing isl Aa ".Imovement of'a driven member.

Vdev'fice-of .A further object is'to provide a specification@referencev being A had to the thereofr My invention relates 4to vibratory means for producing a rotative m'ovement'and has :for onefofits -'objects to provide an 'clectrotresponsive oscillatory actuator 4that shall be 'step rotative -the shoulder 23 of the finger 15. The teeth l27 are arranged and proportioned to coper- J the afore'saidcharacter that shall be equipped wit a simple and reliablecircuit controller for govermng the energization of the electro-responsive actuator.

- -Otheryobjects and advantages of A'my in'- vention set forth hreinafterand in order that my 4invention-may be thor-V oughl understood, I will -now .proceed to descri the same in the followingspecica-- tinand then point. outV thejnovel`features' thereofin appended claims.

Referring tothe drawings:

-Figure 1 is an elevationof a mechanism .A embodying my invention.V Y

A part-pf the same mechanism isshown l in its opposite position .in Fig. 2.

The device illustrated comprises an oscillatory'member 'pivotally mounted at 10 and comprising an arm' 1 1 to which is secured.

a` circuit controller 12 andan armature 13,4

and an arm 14; which is fashioned to-'pr ducea doublepawl structrecomprising fin- 40 gers 16 and 16. A l

,The armature 13` is located 4between a pair of stationary magnets 18 and 19 having core" members 20 and 21.

125` is a star wheel `mounted on a shaft 26 to which'any suitable driven member may be secured 4such 'as for example, a set of countersA for an integrating; meter (not shown).

Each of the fingers 15 ano 16 has an end 22 and a shoulder 23 which are so Vpositioned and proportioned relative to each other and to the center of the shaft 26 as to engage the teeth 27 of the star wheel 25.

Assuming that the magnet 19 is first ener gizcd so that it attracts the armature 13 'to the position shown lnFig. 1 the shoulder 'Patented Jan. s, 1918.

"23. of'finger 16 will engage one of the teeth 27, moving the star Wheel and its connected parts, until the end 22. of-the s ame finger' engagesanother. of the fingers 27 and thereby acts as a stop topi'event further rotation of the wheel.

Ifgthe magnet 18 is-now,energized and the magnet 19 denergized, the armature will swing 1n the opposite direction, moving the arm 14-1nto theposition shown in Fig. 2.

-The end 22 of the finger 15 now acts upon the star 'wheel moving it in the same direction of rotation'as indicated by arrow 30,

until a- -tooth comes into engagement with ate with .the double pawl in the manner de scribed; The finger and shoulders of the pawltareso shaped and arranged that their drivin engagement with the teeth of the star w eel is nearly a straight push witha so l or tube of glass or other insulating material which issubstan'tially horizontal when the arm 11 is midway between the ends of its swing Aand is. provided near its respective ends with sets of contacts 31- and 32 and contains a small quantity of mercury or' other conducting Huid. When the arm is oscillated into the positionshownin Fig. 1,'

the contacts 31 are-disconnected while the mercury or other (':onductingfiuid in the tube'interconnects the terminals 32. When the mechanism occupies the position shown Ain Fig. 2 the-contacts 31 areV Vconnected instead of the contacts 32.' i

' By connecting the contacts 31 in a circuit 35 ofthe -m'agnet 19 andthe contacts 32 in a' circuit 36 of the -magnet 1 8, as shown diagrammatically.in Fig. 1, the. circuits will Vbe completed in alternation and the Abell crank lever oscillated so as to produce a step by step movement of the star wheel.

This application is a continuation in part of my copending application Serial 'No. 784,342 filed .August 12, 1913, and assigned to Electric Weighing Company.

What I claim is: l. A vibratory actuator comprising in combination, a driven star wheel,'a bell crank -lever comprising a double pawl near the cuter end of one 'arm of the lever, an armaturc near the outer end of the other arm of the lever, electro-magnets on opposite sides conducting` liquid in the tube adapted to se lectively engage the contacts A stationary' magnets adapted to oppositely influence the armature, and a pawl arm fashioned to provide a pair of fingers disposed on opposite sides of the star wheel, each of said fingers having an actuating projectionvand a stop projection.

3. A vibratory actuator comprising inv combination, a driven star wheel, an actuating pawl therefor, an oscillatin arm connected with and depending vertically from the pawl, an armature therefor, a: contactcarrying tube extending 'transversely of the arm, conducting liquid inthe tube adapted to selectively engage the contacts, and stationary nagne'ts adapted to oppositely inluence the armature.

lIn witnesswhereof Ihave hereuntoset my hendin the presence of two subscribing witnesses, this 13 day of-Ail' st, 1914.
